PACKAGE LIFTER.

Application filed February 11, 1922.

To all "IO/1.0 m it may concern Be it known that I, CHARLES ihHOLA, a citizen of Finland, residing at Detroit, in the county of ayne and State of l\lichigan, have invented certain new and useful Improvements in Package Lifters, of which the following is a specification.

This invention relates to improvements in package lifters and its. object is to provide novel means for placing or removing packages upon or from store shelves, store house shelves, shelves in public checking rooms and the like. 7 The device is adapted more particularly for moving more or less bulky packages.

More specifically the invention consists in the combination and arrangement of parts to be hereinafter fully described, pointed out in the appended claims and illustrated in the accompanying drawing which forms a part of this application and in whichi Fig. l is a top plan view of the package lifter, the dotted lines denoting the open position of the jaws.

Fig. 2 is an enlarged sectional view taken on line 2-2 of Fig. 5, the supporting arm being folded.

Fig. 3 is a view similar to Fig. 2 but with the movable parts in an altered position.

Fig. 4 is a cross section taken on line 44 of Fig. 5.

Fig. 5 is a longitudinal sectional view through the lifter.

Like reference characters denote corresponding parts throughout the several views.

The lifter comprises the elongated sectional barrel 1 having its lower or open end resting upon the inverted cap 2 to which it is secured by the screws -3, said cap 2 being stationary and resting upon the rotary cap 4 which is secured by screws 5 to the rotary handle 6, round in cross section, which is provided at one end with the head 7 which is secured by screw 8 to the enlarged end of the rod 9, square in cross section within the handle through a central perforation in which member said rod extends. The said rod extends through perforations in the caps 4, 2 and beyond the caps it is diminished in diameter; it extends through the barrel 1 and within which it is formed with the goose-neck portion 9 through a square sliding block 10, located in the upper end of the barrel which barrel-end is square in cross section, and through the neck 11 of head-piece 12 and into said latter member.

Serial N0. 535,815.

This end of the rod 9 is threaded and passes through a threaded perforation in the block 10 and neck 11. As the rod 9 is rotated in one direction it raises the block 10, neck and head-piece and it lowers said members relative to the barrel as it is rotated in the oppo site direction. The barrel end is square in order to prevent rotation of the block 10 with therod. An expansion spring 14 encircles the neck 11 and abuts the block 10 and the perforated end 15 of the barrel and tends to draw the head-piece toward the barrel. The head-piece is provided with a depending collar 16 that slides over the upper end of the barrel, said head-piece being provided with an extension 17 provided with teeth 18.

The junction of the barrel sections is denoted .by the line 19 and the barrel sections are retained in operative relation by the encompassing sectional sleeve 20, the sections of which are formed with the ears 21 connected by the screws 22, said barrel and sleeve being formed, respectively, with the aligned perforations 28, 24 through which the angular jaws 25, 26 extend that are connected by the hinge 26 the pintle 27 of said hinge being supported by a link 28 that is made fast to the gooseneck portion 9 of the rod 9. The jaws 25, 26 are formed along their relatively remote edges with the longitudinally extending grooves 29, 30 in which the ends of a spring 81 are disposed, said spring being positioned within the barrel. As the rod 9 is rotated it rotates the link 28 and raises or lowers the head-piece and alternately moves the jaws 25, 26 into and out of the barrel or alternately into the positions shown in Figs. 2 and 3, the ends of. the spring 31 moving from one end to the other of the grooves 29, 30 causing the jaws 25, 26 to alternately open and close.

The free ends of the jaws 25, 26 are spaced away from the outer end of the extension 17 and it is by said latter member and the jaws 25, 26 that the package to be moved is engaged, said members being separated sufficiently by the operator manipulating the handle 6 to permit the elements 17, 25, 26 to encompass and impale the package. The operator carries the device in one hand and rotates the operating handle 6 with the other hand and by means of the jaws he is able to pick up and transport packages. A bracket 32 secured to the barrel carries the folding snap arm 33 which is so secured that it is rel, a rotary handle arranged at one end of said barrel, a jaw at the opposite end of said barrel, hinge-connected jaws carried by said barrel and extending through the perforation therein for cooperation with the first named jaw, and connection between said handle and the said jaws for actuating the latter.

2. In a package lifter, a perforated barrel, a rotary handle arranged at one end of said barrel, a jaw at the opposite end of said barrel and adapted to move toward and away therefrom, hinge-connected jaws carried by said barrel and extending through the perforation therein for cooperation with the first named aw, and connection between said handle and jaws whereby the latter are actuated, said connection passing through said barrel.

3. In a package lifter, a. barrel, a rotary handle at one end thereof, a head at the opposite end thereof, a jaw integral with said head, a rotary rod connecting said handle and head whereby movement is transmitted from said handle to said head, said rod being formed with a goose-neck portion, hinge-connected jaws carried by said barrel for cooperation with said first named jaw, and connection between said hinged jaws and the goose-neck portion of said rod.

4. In a package lifter, a sectional barrel, a sectional sleeve encompassing said barrel sections at their junction, said barrel and sleeve being formed with aligned perforations, a rotary handle at one end of said barrel, a head at the opposite end of said barrel, a jaw terminating said head, a rotary rod connecting said handle and head whereby movement of the latter through the medium of said handle is eifected, said rod beingformed with a goose-neck portion, angular grooved hinge-connected jaws arranged in the perforated portions of said barrel and sleeve for cooperation with the first named jaw, a link connecting said hinge-connected jaws and the goose-neck portion of said rod, and a supporting arm carried by said barrel.

In testimony that I claim the foregoing as my own I have hereto aflixedmy signature in the'presence of two subscribing witnesses.
